Population Biology

Wolves eat better when the bunny population increases, but how long does that last? A series of 12 biology lessons uses the sixth installment to explore the predator-prey relationship between bunny and wolf populations. Young scientists...

How do we predict future population growth? Young researchers investigate various factors affecting the size of our population. As they calculate and interpret graphs to determine factors that could potentially affect increases and...

A diagram, data table, and reading passage top this resource. Through it, biology beginners are introduced to the concept of natural selection. They answer some questions and then participate in a simulation using fabric as a habitat and...

How diverse is the world we live in compared to the way things used to be? Young biologists explore diverse organisms and relate the structure of each organism to its ability to survive in our current environmental conditions....

Searching for exciting lesson plans filled with hands-on activities to use in your traditional classroom environment? Look no further! This set of lesson plans for AP Biology covers topics from genetics to evolution, botany to ecology,...

The five agents of evolutionary change are reviewed in this slideshow. Definitions of common terms involved with populations and equilibrium are given, and there are some presentations of Hardy Weinberg equations for common examples of...

Learners explore population genetics, or how populations of species change over time, leading to evolution with a video that brings together the principles of Mendel and Darwin and explains and models the Hardy-Weinberg equation.

How large can a population become? The fifth installment of a nine-part unit teaches young ecologists about limiting factors that determine the carrying capacity of species in the Sonoran Desert. Here is a PowerPoint to help present this...

High schoolers define the following terms: predation, competition, carrying capacity and population. They can explain the patterns of growth and the limitations of growth. Students explain the difference between density-dependent and...

Students explore the effects of different density-dependent and density-independent factors on population growth. They explore how the interactions of organisms can affect population growth. Students explore the pattern of population...
